This is despite the most recent series of seeing an increase in viewing numbers, averaging 1.9million when the previous year was 1.8million.

However, when approached by Metro.co.uk, a spokesperson for CBB stated: ‘The situation remains unchanged; Big Brother is currently contracted until the end of the year, there’s no update on future series beyond 2018.’

This year’s theme is ‘Eye of the Storm’ and is believed to have a retribution theme – which would explain the inclusion of many of the potentials.

We don’t have too long to wait to find out…

Celebrity Big Brother returns later this year on Channel 5.
